Partnership combines Armada’s Galleon modular data centers, the Armada Platform, and the Sovereign AI Grid with Palantir’s Sovereign AI Operating System, giving enterprises and governments a path to run and adapt open-weight models on infrastructure they fully control.
Palantir Technologies Inc. (NASDAQ: PLTR) and Armada today announced a partnership to deliver sovereign AI on infrastructure manufactured in the United States and allied nations, with Palantir naming Armada its Inaugural Certified Modular Data Center Partner. The joint offering combines Palantir’s Sovereign AI Operating System with Armada’s infrastructure layer: modular data centers, the Armada Platform that keeps every deployment under the customer’s control, and the Sovereign AI Grid that connects deployments into a resilient distributed system. Enterprises and governments gain the ability to run open-weight models on compute, data, and physical infrastructure they own and control outright, deployed in months rather than years.
Demand for sovereign AI has accelerated as organizations look to reduce their dependence on hosted models and hardware supply chains outside their control. Palantir’s enterprise and government customers have increasingly asked for infrastructure that keeps model weights, data, and physical systems inside their own security boundary, rather than renting capacity from providers outside their jurisdiction—and for new AI capacity that can come online in months, at sites where power is already available, rather than waiting years for new construction. The partnership extends the Palantir Sovereign AI Operating System Reference Architecture—jointly developed with NVIDIA— to host compute infrastructure customers physically own: open models, adapted on the customer’s own data, running under the customers’ control.
Under the agreement, Palantir will validate and integrate its Sovereign AI Operating System—built on AIP, Ontology, Foundry and Apollo—on Armada’s Galleon modular data centers, with the Armada Platform and Sovereign AI Grid providing control and resilience across every deployment. The joint offering builds on the Palantir Sovereign AI OS Reference Architecture with NVIDIA, extending it to a ruggedized, modular data center. Customers gain the ability to deploy open-weight models, continually adapt them on their own proprietary data, and serve them to Palantir’s platforms entirely within infrastructure that never leaves their control, with the modular data centers manufactured in the U.S. and allied nations.
The Armada Platform, the company’s software layer, distills the latest open-source models, including NVIDIA Nemotron, for fine-tuning and inference on infrastructure the customer owns and controls, without reliance on any external cloud, including any operated by Armada, and can operate fully air-gapped where the mission requires it. It provides continuous, real-time monitoring of each deployment’s power, cooling, and compute. The Sovereign AI Grid connects these deployments into a distributed system, so critical AI workloads never depend on a single site. Together with Galleon hardware and Palantir’s Sovereign AI Operating System, the result is a single integrated stack that customers own end to end.
“Sovereignty is not something you rent. It is owning the weights, the data, and the hardware those models run on—and knowing where that hardware was built,” said Alex Karp, co-founder and CEO of Palantir. “Our ontology gives institutions control over their data, their models, and the inputs they use to fine-tune models. Armada gives them control over the infrastructure those models operate from, manufactured in the United States and allied nations and delivered in months.”
“Palantir makes the software governments and enterprises trust with their most consequential decisions. Armada brings the infrastructure layer beneath it: hardware manufactured in the United States and with trusted allies, a platform that keeps every deployment under the customer’s control without reliance on any external cloud, and the Sovereign AI Grid that connects deployments into a system resilient by design,” said Dan Wright, Co-founder and CEO of Armada. “Together we make sovereign AI faster to deploy, more sovereign, and more resilient—on-grid, off-grid, or fully air-gapped, in months instead of years.”
